UEI seeks damages and an injunction, escalating a broader battle over intellectual property in connected-home technology
Universal Electronics Inc. has sued Amazon in a California federal court, accusing the technology and e-commerce giant of infringing five patents covering remote-control technologies used across smart-home devices, streaming products and household appliances.
The lawsuit, filed on Thursday, alleges that Amazon’s Echo smart speakers, Fire TV streaming devices and other products use technology protected by UEI’s patents without authorization. The complaint also targets applications associated with Amazon’s Alexa voice assistant and Prime Video streaming service.

Scottsdale, Arizona-based UEI is seeking an unspecified amount in monetary damages and an order prohibiting Amazon from continuing to use the technologies it alleges infringe its patents.
The lawsuit puts intellectual property at the center of a dispute involving two companies that occupy different positions in the connected-device ecosystem. Amazon has built a broad consumer hardware and software platform around Alexa, Echo and Fire TV, while UEI has developed remote-control and device-control technologies used to connect consumers with televisions, streaming equipment, home appliances and other electronics.
The patents identified in the complaint relate to remote-control technology for several categories of smart products and appliances, according to UEI’s allegations. The company is asking the court to determine that Amazon infringed the patents and to award damages for the alleged violations.
Amazon and UEI did not immediately respond to requests for comment on the complaint.
The case adds to Amazon’s history of patent disputes involving Alexa and related technologies.
In 2023, a federal jury in Delaware found Amazon liable for infringing patents owned by VB Assets covering speech recognition and natural language processing. The jury awarded VB Assets $46.7 million.
The latest lawsuit is separate from that case and involves five patents asserted by UEI. However, it shows the growing intellectual property exposure faced by technology companies as functions that were once handled by standalone remote controls are increasingly integrated into software, voice assistants and connected-device platforms.
The shift has created a more complicated technology landscape in which a single consumer product can incorporate numerous patented technologies. An Echo speaker, for example, can combine hardware controls, wireless communications, voice recognition and software-based device management, while Fire TV products can integrate streaming, remote-control functions and smart-home connectivity.
That convergence can increase the number of potential patent disputes because companies developing connected products may rely on technologies originally developed for separate categories of consumer electronics.
UEI’s claims also come as Amazon continues to expand its connected-home ecosystem. Alexa allows users to control compatible devices through voice commands, while Echo devices serve as hubs for interacting with smart-home products. Fire TV products extend Amazon’s hardware presence into television and entertainment.
For UEI, the case could have implications beyond any damages eventually awarded if the court finds that Amazon’s products infringe valid patents. A successful injunction could potentially require Amazon to modify affected products or software, negotiate a licensing agreement, or otherwise alter how certain functions operate.
Patent cases can also result in licensing agreements rather than an outright ban on products, particularly when the disputed technology is embedded in commercially important devices and applications. The financial stakes could therefore depend not only on the number of products and services found to infringe but also on the scope and validity of UEI’s patents, the duration of any alleged infringement and whether the companies reach a settlement.
Amazon has faced intellectual property disputes involving several areas of its technology business as it has expanded beyond online retail into cloud computing, consumer electronics, streaming and artificial intelligence. The UEI case is therefore seen as one of the legal challenges accompanying that expansion: the more functions Amazon incorporates into its hardware and software ecosystem, the greater the potential overlap with intellectual property developed by other technology companies.
The lawsuit is Universal Electronics Inc. v. Amazon.com Inc., U.S. District Court for the Central District of California, No. 8:26-cv-02117. The allegations have not been proven in court, and Amazon has not yet publicly responded to the claims.
